GM Ben Cherington was overseeing Boston's international scouting department when the team originally signed Sanchez out of Venezuela in 2001. The 28-year-old right-hander pitched to a 3.86 ERA with 7.7 K/9 and 2.2 BB in 195 2/3 innings split between the Marlins and Tigers this year. Several other clubs have expressed interest in Sanchez as well, according to Silverman.

MLBTR's Tim Dierkes ranked Sanchez as the second best free agent pitcher (behind Zack Greinke) and fourth best free agent overall in his Top 50 Free Agents list.
